Learn what a Denial-of-Service (DoS) attack is, how it works, and effective strategies to prevent and mitigate its impact on your network.

The receiving host checks unreachable applications and ports (sent by design by the attacker) associated with these datagrams and responds back with a “Destination Unreachable” response packet. The attackers may also spoof the return IP address making it unreachable as well. As more and more such packets are received, the host becomes unresponsive to other client requests. ...
In this article we look at the differences between DoS vs DDoS attacks. Includes a look at the measures you can use to spot and prevent them.

Amplified reflection attacks are DDoS attacks that exploit UDP connectionless nature with spoofed requests to misconfigured open servers on the internet.
In the cybersecurity world, Distributed Denial of Service (DDoS), malware, and ransomware get more attention than domain name system (DNS) attacks, but DNS attacks are on the rise. The domain name system, otherwise known as DNS or DNS system, is the system used everyday to map website names to their associated IP addresses. If you've used the internet, you've used the DNS. It works using the DNS protocol and DNS lookups, which is similar to looking up a phone number in a phone book. As you can i...
